ASP.NET: Error saving files into folders using file upload control

Question

I'm trying to save files using fileupload control in asp.net. and i made a condition in which: if the file extension is pdf it won't be deleted from the folder but if it's in png format it will be deleted.

I'm getting the following error after clicking the submit button to save them in the database:

"Could not find file {'C:\Users\user\source\repos\project1\En\files\Drawing1.pdf'.":"C:\Users\user\source\repos\projec\En\files\Drawing1.pdf"}

this is my vb.net:

Does anyone know what is the possible reason?thanks

                    br.Close()

                    InscmdFamilyDetails.Parameters.AddWithValue("@PassportFile", SqlDbType.NVarChar).Value = filen



                End If

            End If

Hi @mush,

You're getting Server.MapPath(Server.MapPath specifies the relative or virtual path to map to a physical directory), but I can tell from the code that you're not saving the uploaded file to Server.MapPath, so the file won't be found.

fuFamilyPassportUploadFile.SaveAs(Server.MapPath("~/En/files/" & filen))

 If fuFamilyPassportUploadFile.HasFile = True Then
            Dim filen As String
            filen = Path.GetFileName(fuFamilyPassportUploadFile.FileName)
            Dim FileExtension As String = Path.GetExtension(fuFamilyPassportUploadFile.FileName)
            'Save File to Server.MapPath
            fuFamilyPassportUploadFile.SaveAs(Server.MapPath("~/En/files/" & filen))
            If FileExtension.ToUpper <> ".PDF" Then

Best regards,
